SPECIFICATION forming part of Letters Patent No. 379,494, dated March 13. 1888.

Application filed April 12,1884. Serial No. 127,686. (No model.)

' provement in Grain-Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention is applicable to grain-binding harvesters wherein cord is employed for binding the grain and a revolving hook is used to tie the cord into a knot.

My invention relates to the construction of the cord-h older and its peculiar arrangement to and cooperation with the revolving knotterhook 5 and the improvement consists in a novel combination and arrangement of devices,hereinafter particularly described. Y

Figurel is an elevation of the knotter mechanism or" a grain-binding harvester, looking from the stubble side of the machine; Fig. 2, a vertical section in theline a: x of Fig. l, looking upon one face of the gear-wheel; Fig. 3, a similar view in the line g/ y of Fig. 1, looking upon the reverse face of the said gear-wheel; Fig. 4, a view similar to Fig. 2, showing the cord-holder, needle, knotter, and cord from the bundle in position for tying the knot; Fig. 5, a similarview of the same parts in position after the knot has been tied and while the cord is being cut; Fig. 6, a perspective view ofthe disk shaped cord-holder wheel, cam-plate, gear-wheel, and shoe of the cord-holder; Figs. 7 and 8, detail views of the shoe of the cord-l holder, Fig. 9, a sectional view of the knotterhook, showing the means for operating the spring-actuated jaw; Fig. 10, a view similar to Fig. 2, showing a modified arrangement of the cord-holder; and Fig. 11, a face view of a further modification of the disk-shaped cordholder wheel and the shoe of the cord-holder.

rlhe knotter-frame A projects laterally and downwardly from a sleeve, A', supported upon the knotter-actuating shaft B and overhung arm C of the binder-gear standard in a manner well known in machines of this class. rlhe knotter-hook D is supported vertically and radially with relation to the shaft B by lugs d d,cast upon the frame, and has secured to it a pinion, D', arranged between the lugs d d,

which engages with a segment-rack, E', formed upon the face of the knotter-actuating gearwheel E, there being as many teeth, less one, on the rack as on the pinion. The rack E occupies only a segmental part of the face of the wheel E, the remaining portion of the face of the wheel being formed with a segmental rim or flange, E, projecting from the face of the wheel, andwhich engages with a plane surface or delay-shoe uponthe hub of the pinion, by which means the knotter is caused to make a complete revolution by the segmentgear, and then held from turning during the remainder of the revolution of the knotteractuating gear-wheel. v

The knotterhook D is provided with a vhinged jaw, D2, which is operated, in a manner hereinafter described, to grip and release the cord at proper intervals and to tie the knot in a well-known manner.

The cord-holder .constitutes a most important part of the instrumentalities employed for tying the knot, and the devices here employed are of simple construction and operate effectively, not only to securely hold the cord,but to deliver it to the knotter when the knot is being tied, and thus relieve the knotter of the excessive strain which would be required to draw a su'rlicient quantity of cord to tie the knot fromthe bundle. This I accomplish in the following manner:

The cord-holder disk F is secured upon Ia shaft, F, j ournaled in alug, d', cast upon the knotter-frame, and has secured to it a gearwheel, F2, which engages with and is revolved by a segment-rack, E, cast upon the face of the gear-wheel E. The number of teeth in the rack being one less than a third of the number of teeth in the wheel F, the latter will be revolved the one-third part of a revolution at each complete revolution of the gear-wheel E. Atriangular-shaped cam-plate, F3, formed with concaved sides or seg mental depressions, is secured to the shaft F against the outer face of the gear-wheel F2, and a beveled flange, E3, formed upon the periphery of the gear-wheel E, is mutilated or cut away opposite the segment-rack E4to permit the cam-plateF3j to turn when the gear-wheel F2 is engaged with the rack E4 and present a new face to the liange IOO E3, and check the further movement of the shaft F during the remainder of the revolution of the gear-wheel E. It will thus be seen that by the partial revolution of the gear-wheel E the shaft F and cord-holder disk F will be moved one-third cfa revolution, and the said shaft and disk will be held stationary during the remaining portion ofthe revolution of said gear-Wheel.

The disk F is provided with aflange, f, projecting from its face,and is formed with notches ff2f3, into which the cord is placed by the needle G. The disk F is secured to a shaft, F', arranged nearly horizontally to hold the face ofthe disk slightly out of a vertical plane and permit its lower edge to project within the path of the needle and the plane in which the cord is laid thereby, and said shaft is also arranged at an angle to project the side of the disk farthest from the knotter-hook across said plane through which the cord is laid by the needle, in order that the notch f', farthest from the knotter-hook, may receive the cord without obstruction from the flange of the disk.

A stationary shoe, H, forming part of a cord-holder, is formed with concentric segmental iianges h h, which straddle and partly encircle the iiange fof the disk F, and with a stud or body, H', which is supported in a lug, d2, of the frame, and is moved longitudinally therein, with an elastic pressure against the face and iiange of the disk F, by a dat spring, I, secured at one end to a lug, d3, upon the frame, with its free end bearing against the end of the body H of the cord-clamp. The cord-holder shoe H is also formed with an inclined extension or lip, H2, which projects at an upturned angle from the face of the disk F, opposite the notch into which the cord is placed, and guides the cord surely therein.

The knotter-hook D is formed with `a hollow spindle, D4, through which passes a stem, D3.

The lower end of the stem is slotted to receive the hinged jaw D2 of the knotter-hook, and its upper end is secured to a yoke, D5, through which passes the free end of a vibrating springplate, D". The outer end of the spring-plate D6 is securely bolted to a lug upon the frame A, by which means the hinged jaw is pressed firmly upon the xed hook D. A frictionroller, D7, is journaled upon the free end of the spring-plate D, and a cam-spur, e, upon the knotter-actuating gear-wheel serves to lift the hinged jaw at the proper moment to grasp the cord when the knot is being tied.

By the above-described means for supporting and operating the knotter-hook it will be readily seen that a very short spindle may be employed and a simple, strong, compact, and effective construction and arrangement of parts may be attained.

The entire knotter-hook spindle and stem will extend across much less than half the diameter of the knotter-actuating gear-wheel, and the jaws may be opened and closed at proper intervals to receive, grip, and release the cord by mechanism arranged beneath and upon one side only of the knotter-actuating shaft.

Various modifications can be made in the cord-holder without departing from my invention, as, for instance, it is obvious that double concentric anges may be formed upon the face of the holder-disk, and a cord-holder shoe having but one flange may be employed to rest within the channel formed by the double iianges of the disk, as shown in Fig.- 11.

Another modication of the cord-holder is shown in Fig. l0 of the drawings,wherein the cord-holder disk F is nearly in a horizontal position and the shaft F of the disk arranged radially to the knotter-actuating shaft in a nearlyvertical position. The notches are formed in the upper face of the iange or rim disk, and a cord-holder disk similar to that rst described engages with the liange or rim of the disk. A beveled pinion, L3, secured to the upper end of the shaft F', is revolved intermittently one-third of a revolution by a segment-rack, L4, and held from revolving during the remainder of the revolution of the wheel E by the flange L5, and a delay-shoe, L, similar to that first described, Will serve to hold the cord-holder disk successively in its three positions. The shoe may be held against the face of the disk F by a spiral spring, LS, in this instance.

The operation of the knotter is too well known to require detailed description here, and the operation of the cord-holder will also be readily understood from the foregoing.

When the bundle has been bound,the end of the cordis left and held securely in the holder, and when the needle encircles the bundle it approaches the holder and brings the spool portion of the cord over the knotter-hook and lays it thereon, and also across the face of the IOO disk and into one of the notches of the holderdisk. Vhen the knotter-hook has made about one-third of a revolution, the cord-holder disk will begin to revolve and carry the cord beneath the cord-holder shoe to firmly hold it. The disk revolves toward the knotter-hook, and thus delivers the cord thereto to form the knot, which will relieve the knotter mechanism of undue strain. When the cord-holder disk shall have completed a movement, or one-third of its revolution,the knot will have been formed and the cord cut between the knotter and cord-holder, leaving the end ofthe cord rmly clamped by the holder ready to bind another sheaf.

The hinged jaw of the knotter-hook is raised by the pressure of the cam upon the frictionroller at the end of the vibrating spring-plate at'the proper interval to catch the cord between the bundle and the holder and form the knot in a well-known manner.

I claim as myinvention and desire to secure by Letters Patentl. In a knotting mechanism for grain-binders, the combination, with the cam and gear wheel having gear-segments and delay-rims IIS disk, provided with a segment-rack serving to partially rotate the disk, and with a muti- 15 lated flange or rim permitting such partial rotation and acting on the cani-plate to hold the disk in the intervals between said partial rotations, substantially as described.

In testimony whereof I have hereunto set my 2o hand this 20th day of March, A. D. 1884.

JOHN F. SEIBERLING.
